First of all I am new to arduino. I am planning to make panoramic tripod head (en.wikipedia.org/wiki/Panoramic_tripod_head) and I was searching in internet for a suitable controller and I came to know about arduino. I like self programmable feature. So my problem is I don't know which board I have to select for my project. I have to connect these things to the board 1. two unipolar stepper motors2. one 2X16 LCD display3. one 2X2 key pad4. one out pin to connect to a IR LED ( To trigger the camera, my camera is supported a remote controller)5. two home-position sensors (To Initialize/home-position the panoramic tripod head )So please help me to find out a correct board.

just for the same purpose I began with the standard board then switched to a Arduino Nano (just to get a smaller footprint), two easydriver stepper controller, two bipolar steppers, serial LCD 4x20 and a Wii Nunchuck, no sensors for end/limit position, I trigger the cam via a cannibalized wired remote cable

i was thinking about something similar, and i figured out that to have a good mechanic is the most important part. the rest should be easy. so i would start with a concept for a very precise turning head.
